The following projects were completed as a part of a year long NASA-funded research internship with the Princeton TigerSats Lab organized by the New Jersey Space Grant Consortium. 
Electrodeposition Microgravity Experiment Platform (in progress)

This experimental platform was designed in support of PhD level research. The design comprises of a precision rotary indexing system that allows for accurate alignment of a sample with a microscope, all controlled by a RaspberryPi computer and driven with a Nema 8 stepper motor.

The main design goals of this project are to achieve sub mm precision and matching accuracy at the appropriate sample wheel diameter. Being an enclosed experiment platform, it was crucial to ensure the accuracy of the system is maintained after flight to orbit conditions. This is achieved by using a small form factor absolute encoder.

The project is currently in development as I work to prepare it for a potential sub-orbital test launch.

Custom Nanoracks MaxIQ Payload Enclosure
This is TigerSat's first first all-custom Nanoracks-compatible enclosure.

The design uses machined aluminum top and bottom caps with an aluminum sheet metal surrounding. The front face plate is slotted to accommodate the larger sized MaxIQ payloads. Within the enclosure are 17 MaxIQ STEM payload kits.

COTS Nanoracks Nanolab Enclosure
Utilizing Nanoracks' Commercial Off-The-Shelf (COTS) Nanolab ISS experiment platform, I designed an enclosure capable of housing 12 standalone MaxIQ Sensor Payload Kits.
The design incorporates stacked hex spacers and a Common Signal/Power Bus to structurally support the payload kits, ensuring stability and reliability during experimentation.
With modularity in mind, the design allows for easy expansion from a 1U to 1.5U or beyond, as seen in the previous project, providing flexibility to accommodate evolving research needs.

The project was presented at the inaugural Maine Space Conference. Read more here.
